Thor can wield both Mjolnir and Stormbreaker without dying, or it causes him to strain his health. It is unfortunate, but the fact that being mortal is what kills Jane for being Mighty Thor makes the original
Superhuman Strength: As a Valkyrie, Jane possesses superhuman strength like all Asgardians. She is strong enough to hold and lift a car over her head.
She was a breast cancer victim until she discovered Mjolnir and its transformational qualities. Because she knew there was an end in sight, she was able to push herself even harder. Even in her immortal Thor body, she's aware of her own humanity, and that's what makes her stronger than Odin.
As Mighty Thor, she has almost the same powers as Thor Odinson himself, except she can wield the hammer (Mjolnir) better than others. But even with all the godly strength, there's one caveat in her turning into a God - the moment she puts the hammer down and stops being the Mighty Thor, she returns to her dying body.
Yes, Jane handles Mjolnir better than he does but he still has a lot more experience than she does, but he's gone up against tons of different villains and learned how to defeat them, which is something Jane never really got the opportunity to do since she wasn't Thor for very long.
The two brothers, clouded by pride and hate, send the Destroyer after Jane, despite the new Thor saving others and fighting for what's right. While she gets thrown around, Thor refuses to back down, which is another reason why Jane is worthy of being Thor.
Despite Sif's status as an excellent warrior, Mighty Thor would clearly best her. Sif has no major ranged attacks. While Sif would likely beat Jane Foster in hand-to-hand combat, Jane's abilities of flight, lightning generation, and projectile weaponry would send the Goddess of the Hunt crashing to the floor.
Hercules / Zeus
He ranks above Thor here because he's technically the stronger of the two. In fact, he is considered by many authorities to be the physically strongest character Marvel has ever created.
The most powerful Thor variant is Ultimate Thor, who's real name is Thorlief Golmen. Golmen discovers he is the most recent reincarnation of Thor Odinson and begins his journey as the new God of Thunder. This version of Thor was less reliant on Mjolnir as a power source.
However, the film also implies that the hammer only sees Jane as worthy because Thor unintentionally revised the rules of Mjölnir, giving it the power to protect her. Captain America didn't need anything special for the hammer to see him as worthy – he's able to wield it without issue in Avengers: Endgame.
In a moment of wistful affection for his girlfriend, Thor asked his trusty hammer to always protect Jane, and in doing so unwittingly enchanted Mjolnir to do just that. Just like Thor's father Odin once enchanted the hammer to only be lifted by someone who is worthy, Thor cast a spell that let Jane use its powers.
During a confrontation with a creature known as Mangog, who was trying to destroy the city of Asgardia at the time, Jane sacrificed Mjolnir to defeat the monster, giving up her life in the process (“Mighty Thor” Vol. 2 #705).
Upon saving Asgard from Ragnarok, Odin forces her to relinquish the hammer to Donald Blake so he can become the new Thor. This resulted in Jane losing her powers, but she was allowed to remain on Asgard and keep her goddess status since she later falls in love with and marries Thor.
Both Jane and Thor started to withdraw from each other, they both were experiencing the loss of their relationship. It was a mutual breakup because they both left each other, yet the love still remained. Often heartbreak can lead someone to harden their hearts to love.
Thor begs Jane to put down the hammer so that they can have more time together. But when Thor is nearly killed by the villainous Gorr the God Butcher (Christian Bale), Jane transforms into Thor to save her true love.
Who can beat Thor? In his normal form, with his classic power levels, Thor has openly stated that the Hulk is one foe he can't beat.
Thor is great at close-range combat, too, which is one of Wanda's weak points. Captain Marvel and Captain Carter were able to get in a few blows before succumbing to the Scarlet Witch, and that is because they got close enough to her to do it.
Moon Knight's power level is often up for debate, but every night he demonstrates that he is capable of taking out each of the Avengers.
Thor doesn't always save the day in Marvel Comics, and some of his biggest losses include falling to Thanos and Gorr the God Butcher.
While Thor is powerful and his strength is said to be unmatched, he is not strictly immortal like other mythological gods. He is susceptible both to aging and to being killed in battle. Like other Norse gods, he must consume special apples kept by the goddess Idun to keep from aging.
Superhuman Stamina: His stamina is almost limitless. Thor survives the Time Stone of time. While still aging physically, he retains his youthful appearance far longer than humans, barely changed after Thanos used the Time Stone to age by several centuries, and will only grow stronger the older he gets.
What Is Jane Foster's Weakness in The Mighty Thor Comics? In the comics, Jane is battling cancer when she picks up Mjolnir for the first time. This allows Jane to transform into The Mighty Thor, giving her the energy she's lost because of her illness, as well as gifting her with godlike strength and other abilities.
It is revealed that Thor and Jane broke up sometime after the events of Avengers: Age of Ultron. When a fangirl tells Thor she's sorry that Jane dumped him, he sheepishly replies that it was a mutual breakup.
Jane decided to keep using Mjolnir as the MCU's Mighty Thor, however, because she wanted to use what little time she had left to do something that mattered, and she eventually died helping Thor stop Gorr and ascended to Valhalla.
